SELF-CLOSING- STANCI-IION.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed May 14, 1910. Serial No. 561,873.

To all whom 2'25 may concern:

Be it known thatI, HARRY H. Rune, a citizen of the United States,residing at Marathon, in the county of Cortland and State of New York,have invented certain new and useful Improvements in Self-ClosingStanchions, of which the following is a specification.

This invention relates to stanchions and has for one of its objects toprovide means adapted to be tripped by the animal whereby the stanchionwill be automatically closed and locked.

Another object is to provide means for locking the stanchion in closedposition.

1V ith these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter more fully described and pointed out in the claims, but itwill be understood that changes in the specific structure may be madewithin the scope of the claims, without departing from the spirit of theinvention.

In the drawings: Figure 1 is a front elevation of a stanchion in openposition. Fig. 2 is a front elevation of a stanchion in closed andlocked position. Fig. 3 is a cross section on the line 33, of Fig. 1,looking in the direction of the arrows.

Referring to the drawing it will be seen that the stationary frame ofthe stanchion is composed of the upper and lower stringers 1 and 2 andthe uprights 3.

The movable frame of the stanchion comprises the downwardly convergingside members 4, which are connected at their up per ends by the parallelspaced strips 6. The lower ends of the side members 41; of the movableframe are connected by the cross piece 7. The upper and lower connectingstrips of the movable frame are swiveled at 8 to the stringers 1 and 2,and extending between the upper and lower cross pieces 6 and 7, anddisposed to one side of the line of the pivots 8, is a bar 9, whichconstitutes the stationary stanchion bar. A movable stanchion bar 10 hasits lower end 12 beveled at one edge and seated within a recess 11,formed in the lower cross piece 7. The upper end of the movablestanchion bar is adapted to play between the parallel strips 5 and 6 atthe upper end of the swiveled frame.

A bolt 13 is pivoted to the side bar 4 of the stanchion frame near theupper end thereof, and is adapted to fall to one side and engage theouter edge of the movable stanchion bar 10. The bolt 13, when in itsuppermost position is seated within a notched recess 13, formed in theunder face of the upper stringer 1, and in such position prevents therotation of the swiveled frame until the animal has passed its headbetween the stationary bar 9 and the movable bar 10. When the bar 10 isreleased from the position shown in Fig. 1, the bolt 18 falls andengages against the edge of the said bar. The release of the bar 10 isaccomplished by contact of the animal with the closing mechamsm.

The closing mechanism comprises the angle lever let pivoted at its angle15 to the movable bar 10, and having its arm 16 provided with alaterally projecting pin 17 adapted to engage and slide in a slot 18formed in the outer end of the link 19, pivoted at one end to the sidebar 4: of the movable frame. The arm 20 of the angle lever is providedon its outer end with a semi-spherical enlargement 21, which when thesaid lever is swung to the position shown in Fig. 2, will be engaged andheld by the spring finger 22, secured on the stationary bar 9. The fiatside of the weighted enlargement engages the bar 9 and the rounded sidefits snugly within the embrace of the spring finger, until it isreleased therefrom by the animal. hen the animal comes in contact withthe arm 20 of the angle lever it will be pushed from the spring fingerand by gravity fall into a vertical position, as shown, and through thearm 16 push against the link 19. This will cause the pin 17 to movealong said slot until it bears against the end wall of the horizontalportion of the slot 18, and pressing thereagainst communicate movementto the bar 10 forcing the said bar into upright or operative position.Upon the bar 10 assuming a vertical position, the latch 13 will fallinto the position shown in Fig. 2, against the edge of the bar 10. andhold the said bar in locked and operative position. The animal cannot,then, remove its head from between the stanchion bars, until the saidlatch is raised by hand. In the initial movement in the fall of thelever 14, the pin 17 rides in the horizontal portion of the slot 18,until the said lever is in an almost vertically depending position, whenthe pin strikes the inner end wall of the slot. This causes alost motionbetween the lever and link, and the impact against said end wall forcesthe bar 10 into its operative position. The slot 18 is open at one endof its vertical portion, for the purpose of readily removing the linkfrom engagement with the pin, when it becomes necessar 1 to inspect orrepair the parts.

To open the stanchion, the latch 13 is first raised by hand, and seatedin the recess 13 in the upper stringer, and the lever let raised untilits weighted end is embraced by the spring finger. This movement of thelever produces a reversal of the movement above described. Theengagement of the latch 13 within the recess 13 provides a locking connection between the stationary frame and the movable frame, to preventthe rotation of the movable frame. This insures the swiveled frame beingin the proper position to receive the head of the animal, and the disengagement of the said parts permits the animal to readily move its headfrom side to side.

From the foregoing it will readily be seen that I have provided a simpleand efficient stanchion, and one which is closed automati cally whentripped by the animal. Also, I have provided a stanchion which insuresthe steady position of the movable frame so as to present the openingfor the animals head in the proper position.

lvhat is claimed is:

1. A cattle stanchion comprising a stationa ry frame, a movable framerotatablymounted in the stationary frame, a stationary confining memberin the movable frame, a movable confining member in the movable frame,said movable confining member adapted to move toward and away from thestationary confining member, a lever pivoted to the movable confiningmember and comprising a horizontal and a vertical arm, said horizontalarm adapted to extend across the confining members and detachably engageat its free end with means on the stationary confining member, a linkpivoted at one end to the 4 movable frame and having its other endpivotally and removably connected to the vertical a m of the lever,whereby when the lever is released from the stationary confining memberby contact of an animal, the said levcr will fall and draw the movableconfining member into operative position.

2. A cattle stanchion comprising a stationary frame, a movable framerotatably V mounted in the stationary frame, a stationary confiningmember in the movable frame, a movable confining member also mounted inthe movable frame, a lever comprising a longer and a shorter arm andmounted on said movable confining member, a weight on the free end ofthe longer arm adapted to engage and be held by a means on thestationary confining member, a link pivotally connected to the movableframe at one end thereof, and having its other end formed with an openended angular slot, a pin on the shorter arm of the said lever adaptedto slidably engage in the slot of the said link, whereby the levercomn'iunicates movement through its shorter arm and the said link tomove the movable confining member into operative position, when the saidlever is released by contact of an animal.

In testimony whereof I atlix my signature, in presence of two witnesses.
